GAS OR VAPOR BURNER.

SPECIFICATION forming part of Letters Patent No. 533,594, dated February5, 1895.

Application filed April 16, 189 Serial No. 507,628. (No model) To allwhom it may concern: sired construction, but which is preferably Be itknown that I, HENRY A. HOUSE, aciticomposed of a hollow reservoir intowhich a zen of the United States, and a resident of hydrocarbon liquidin regulated quantity is Bridgeport, in the county of Fairfield andintroduced through the pipe B. 5 State of Connecticut, have inventedcertain The interior space of the generator is dinew and usefulImprovements in Gas or Va- .vided by transverse webs or partitions Cthat per Burners, of which the following isa speci- "extend partiallyacross the same and form a fication, reference being had to the drawingsserpentine passage with an outlet at pipe D accompanying and forming apart of the through which the vaporized hydrocarbon is [0 same.conducted to the burner.

The main object of my improvement is to so Above and partiallysurrounding the anincrease the capacity of a single burner thatit nularchamber E is a mixing chamber H may have a much greater range of heatingefwhich is provided with a series of openings feet and available,without waste of fuel or I around its base and which extends up into cthe necessity of adjustment or attention for another chamber J alsoprovided with openproducing any desired amount of heat within ings Kround its base.

Sufficient gas findsits way around the valve stems into the chamber F to maintain a flame atthe end of this tube, the amount of gas being regulated by a screw plugT provided with a slot. In the use of the burner a small quantity ofaqueous vapor sometimes passes through the valve openings and by itssudden expansion under the intense heat, extinguishes the main flame.The pilot flame, however, from its position is not afiected and servesto relight the gas as soon as the disturbance has ceased.

The operation of the device is as follows: Liquid hydrocarbon in anamount proportioned to the steam power to be generated is admitted tothe generator A and being vaporized therein, by heat applied theretowhen necessary, passes to the burner. The pressure of this vapor willraise to a greater or less extent say, the lightest valve, and theescaping jet draws up through the holes in the mixing chamber H and thenozzle J sufficient atmospheric air to maintain a perfect combustion ofthe vapor. One valve may regulate the pressure necessary for producingsay, from one to five horse power. If a higher power is required thequantity of oil is increased and the pressure of vapor in the burnerproportionately raised. If a single valve were relied upon to regulatefor this increased pressure, it would be found that the jet of escapingvapor would be too thin to draw up enough air for perfect combustion,but the increased pressure raises the two lightest valves so that theair is now drawn in by the combined effects of two jets. In this way bythe use of a plurality of valves and the proper adjustment of the same,one burner may be used and perfect combustion maintained for any numberof horse power.

A special advantage is secured by making, in this kind of burner, thechamber E in annular form with a central air passage through it, as itprevents eddying of the gases, and affords a means of supplying air toboth sides of the jets.

It will be understood that such of the heat as is not absorbed by thegenerator is utilized for generating steam or any other purpose.

Having now described my invention, what I claim is v1. In an apparatusfor burning a gas or vapor, the combination with a source of gas subjectto variations of pressure, a chamber into which the gas or vapor isintroduced and a mixing chamber into which the gas chamber opens througha series of orifices, of a plurality of weighted valvesnormally closingsaid orifices and adapted to be raised by the pressure of vapor or gaswithin the gas chamber, as set forth.

2. In a gas or vapor burner, the combination with a chamber into whichgas or vapor is introduced having a plurality of independent anddifierently weighted valves normally closing orifices for the escape ofgas from the chamber and adapted to be raised by the pressure of gas orvapor within said chamber.

3. In a gas or vapor burner, the combination with a chamber into whichgas or vapor is introduced, and a second chamber beneath the same, ofone or more valves normally closing orifices for the escape of gas andweights contained inthe lower chamber and connected with the saidvalves,as set forth.

4. In an apparatus for burning a gas or vapor, the combination with asource of gas subject to variations of pressure, an annular chamber intowhich the gas or vapor is introduced and a mixing chamber into which thegas chamber opens through a circular series of orifices in the top ofthe gas chamber of a plurality of weighted valves normally closing saidorifices and adapted tobe raised by the pressure of vapor or gas issuingthrough the orifices, as set forth.

5. The combination with the gas chamber E and the lower chamber F of oneor more valves controlling orifices in the top of the gas chamber, stems0 extending down into chamber F and weights of different sizes attachedto said stems, as described.

6. The combination with the annular gas chamber E having a central airpassage, and the lower chamber F of valves controlling orifices in thetop of the annular chamber and weights contained in the chamber F andsuspended from the valves by stems passing through the gas chamber intothe chamber F, as set forth.

7. The combination with the annular gas chamber E having a central airpassage and the lower chamber F of valves controlling orifices in thetop of the annular chamber, weights contained in the chamber Fandsuspended from the valves of stems passing through the gas chamber intothe chamber F and a pilot burner in proximity to the valved controlledorifices supplied with gas from the lower chamber F, as set forth.
